Then the tax authorities will not be able to accuse you of having made an NFT token on your own.
Making your own NFT tokens is not illegal. Nor is selling a new token for $10,000 more suspicious than selling a $10 token for $10,000.
First of all, creating tokens and placing them on NFT trading platforms has a commission, and in most cases it is easier to buy someone else's token for $10 than to make your own tokens.
Selling new tokens is always suspicious, because your tokens will have nothing (ecosystem, project and so on). If you are a famous artist or designer, I agree with you, but in other cases I would use ready-made NFT projects.
